Application filed March 29, 1915. LSerial No. 17,619.

- Machines, of which the following is a specification.

This invention relates to a dish washing machine and especially to a dish washingmachine which is adapted for family use.-

It is an object of this invention to provide a dish washing machine which does not require handling of the dishes except -to place them in the washer and remove them therefrom.

It is another object of this invention to provide a washing machine which vdoes not require mechanical agitation of the water during the time the dishes are being washed.

1t is a further object to provide a dish washing machine in which water can be used, the temperature of which is at t-he boiling point. l s

1t is` a further object toprovide a dish washing machine in which a basket hav ing two compartments is provided, one compartment adapted to contain dishes and an- `other for' silverware,

and also to provide a receptacle for kitchen receptacles such as pots, kettles and pans. p

VI attain these objects by means of the dish washer illustrated in ythe /accompanying drawing, in which:

igure 1 is a perspective view of anl embodiment of tical' cross section through the cabinet. Fig.

3 isa horizontal section, through the dish adapted to contain 4%' compartment. Fig. 4 1s a perspective view illustrating a modied form of dish and silverware basket. view illustrating the pot and pan receptacle.

More specifically, 5 designates clear water.

6 is a reservoir for soapy water and 7 the i cabinet adapted .to washed. l

Clear water reservoir 5 is here shown as cylindrical' in form, but may have any other form, and is provided with a sight indicator 8 which is comprised of a glass tube connected at thel lower'and upper'ends to the reservoir, so that the level ofthe water in thereservoir may be observed.

A conduit 9 end of lthereservoir and to a 'l' 10. Valve contain the utensilsto bev residing at iny invention. Fig. 2 is a ver- Fig. 5 is a perspective a reservoir is connected at the lower l1 for controlling the flow of water from rese ervoir 5 is located in conduit 9. -VA reservoir 6, here shown as cylindrical inl form but which maybe of any other form, has secured thereto aysight indicator 12 of a construction similar to sight indicator 8.

'A' soap dispensing reservoir 13 isconnected to a measuring receptacle 14. by means of a valve controlled conduit l5, and measuring receptacle 14 is connected to reservoir 6 by a valve controlled conduit 16,.`

Connected to the lower `end of reservoir 6v and to 'l' 10 is a conduit connected therein. Connectiiig T 10 and the cabinetis a conduit 18.

, Pipe 19 conducts Huid fuel to burners 2() and 21 disposed beneath reservoirs 5 andG respectively for heating the water in the reservoirs.

The dish washing cabinet 7 consists of a rectangular body divided into two compartments by a wall 22. The upper compartment is provided with a hinged the basket 24 may be' introduced into and removed from the of spray tubing is composed of a closed systenr of, tubing having perforationsy adapted cabinet. p Disposed inhori-v zontal planes within the upper compartment are spray tubing 25, 26 and 27. Each layer 17 with a valve 48 cover 23 whereby to allow thin streams of water to issue there-v v from; they may be formed of pipes 28, 29, 30, 31- and 32, connected by elbowsand by means of a 'Il' 33 to conduit 18. r

The basket 24 is constituted of wire netting with abottom 34 of Wood, having perforations 35 disposed therein. The side wall of the basket is dicated at 36, so that silverware may be 1ntroduced into the bottonil of the basket.

open ,at the lower end as in-' Suitable handles may be provided for cary rying the basket when removed from the cabinet as indicated at 37 and 38 in the.

modified Fform shown in Fig. 4. Within the basket are horizontally; disposed slats of wood l39,40 ...naar Wh ofthe dishesy with the -b'eenfound'that if the dishes are permitted to contact with' the wire, rust spots are formed thereon, wherefore, I have preferably provided `the wooden slats to prevent spotting of the dishes. The modifiedvform vof basket shown ,in Fig. 4 is not provided with wooden slats, but is, otherwise, the same as the preferred form shown in rFig..2.' A conduit 42-is connected to the partition vwall 22 and to bypass 'pipe 43 having a ich vprevent contact wire netting. It has side walls of cabinet 7 I provide valve 44. A valve 45 having a long stem 4G so that it may be operated from the outside of the cabinet, is connected to control conduit 42.

A hinged door 46 is provided for the lower compartment of the cabinet, so that the pot and pan receptacle 47 may be introduced therein. Receptacle 47 is iinperforate and provided with suitable handles for carrying the same when the receptacle is removed from the cabinet. Ilpon one of the a hinged shelf 49 upon which the receptacles, especially the dish receptacle, may be placed when removedifrom the cabinet.

My improved dish washer is used by removing the basket 24 fromthe cabinet, placing the dishes therein. in the upper compartment, the silverware in the lower compartment. The basket is now carried to the cabinet 7, placed in the upper compartment and cover 23 closed. If it is desired to wash the kettles and pans and other cooking utensils, they are. placed in receptacle 47 which is placed in the lower compartment of the cabinet 7 and the door 4G closed. Valve 48 is now closed to prevent the liquid from entering the cabinet from reservoir 6. The valve in conduit 15 is opened permitting the soap which is preferably liquid soap, to fill measuring receptacle 14. Valve conduit 15 is then closed and valved conduitK 16 opened to permit the soap toy enter the reservoir (i. Sufficient water is'admitted to reservoir (i for one washing of dishes. In actual practice reservoir G will be constructed to hold about five gallons of water, while the soap reservoir 13 will hold approximately one gallon, and the measuring receptacle 14 having a capacity of one pint. Valve 11 is closed and reservoir 5 then filled with water. Reservoir 5 will have a capacity of approximately live gallons.

Burners '20 and 21 are now lighted to heat the water in reservoirs 5 and (i. IVhen the water has reached the boiling point valve 48 is opened, admitting the hot soapy Water through conduits 17 and 18 to the spray tubing 25, Q6 and 27, thereby spraying the dishes with hot soapy water, the temperature being that of boiling water, whereby the. dishes are thoroughly cleansed. The,

water from the dishes passes over the suverware in the lower compartment, and if it is not desired to clean the kitchen utensils, valve 45 is closed and valve 44 opened, permittingthe water to drain to the outside, where it may pass into a receptacle such as a. bucket, and be used for washing the iioors. If it is desired to wash the kitchen utensils, valve 44 is closed and valve 45 opened, admitting the hot water to receptacle 47. To rinse the dishes, valve 11 is opened, permitting the hot clear water to be sprayed over' the dishes through spraying and 27.

If desired` conduit 9 may be connected to the range boiler and water used from the range boiler instead of from a special reservoir. After the dishes have been rinsed, cover 23 is lifted and the basket 2.4 removed from the cabinet and placed upon the shelf 4S. Due to the high temperature of the water, the dishes dry and they are now in condition to be again used'. It may be found convenient to wash the dishes just before using them on the table, when the heat from the water will have warmed them, so that a warming oven will not be necessary where my dish washer is used.

lVhat I claim is:

In a`dish washing machine, the combination of means for supplying washing Huid, a cabinet divided by an imperforate horizontal partition into an upper and lower chamber, spray conduits disposed on the walls of said upper compartment and connected to said means for supplying the washing fluid. a perforate basket removably mounted in said upper compartment, a drain conduit mounted in said horizontal partition connecting the upper and lower compartments, a by-pass conduit connected to said drain conduit and leading outside of said cabinet` and valves for controllingv said drain conduit and said by-pass conduit.

In witness that I claim the foregoing I have hereunto subscribed my name this 10th day of March, 1915.
